Clayton Coleman e4e8608ba0 Use CodecFactory.WithoutConversion() everywhere 
Clarifies that requesting no conversion is part of the codec factory, and
future refactors will make the codec factory less opionated about conversion.

Clayton Coleman c8f7d5017d Make RequestScope be a pointer consistently for better memory use 
RequestScope is a large struct and causes stack growth when we pass
it by value into multiple stack levels. Avoid the allocations for
this read only struct by passing a pointer.

Clayton Coleman 8541248953 Avoid allocations when building SelfLinks and fast path escape 
A self link should only require one allocation, and we should skip
url.PathEscape() except when the path actually needs it.

Add a fuzz test to build random strings and verify them against
the optimized implementation. Add a new BenchmarkWatchHTTP_UTF8 that
covers when we have unicode names in the self link.

```

```

Saves 3 allocations in the fast path and 1 in the slow path (the
slow path has to build the buffer and then call url.EscapedPath
which always allocates).

Clayton Coleman 78a40897c5 Unify runtime.SerializerInfo with negotiate.AcceptedMediaTypes 
There was no reason to have two types and this avoids ~10% of allocations
on the GET code path.

Clayton Coleman 9006e59e3b IsListType uses reflection and is expensive for hot paths 
IsListType was causing ~100 allocations for a non list object. It is
used in a wide range of code, so perform a more targeted check.

The use of `%#v` in a hot return path for `fmt.Errorf()` was the main
victim.

Replace `%#v` with a typed error and create a cache of types that are
lists with a bounded size (probably not necessary, but safer).
